Final answer:
The price elasticity of demand for cigarettes ranges from 0.3 to 0.5, indicating that the demand is inelastic. If cigarette manufacturers increase prices, their revenue will increase due to the inelastic nature of demand.
Step-by-step explanation:
The price elasticity of demand for cigarettes ranges from 0.3 (the lowest end of the range in absolute value) to 0.5 (rounded to two decimal places). The demand for cigarettes is considered inelastic because the price elasticities in this range are less than one (in absolute value). If cigarette manufacturers raise prices, their revenue will increase. This is because the demand for cigarettes is inelastic, meaning consumers are less responsive to price changes, so an increase in price leads to a smaller decrease in quantity demanded compared to the increase in price.
